Stop stop, this has nothing at all to do with saving money (after all, this is about the indoor climate, I would gladly give up a few Hue lamps for that). Not nice!
If you google the thing, one of the first things you find is a post in a forum about Zehnder exchangers and related problems concerning odor nuisance and distribution in all rooms.
At first, I thought, okay, then I’ll just turn off the humidity function, which was quickly done after I understood that the entire filter system is different and not just a (cost-effective replaceable filter).
That’s why I have concerns and further questions on the topic. I definitely don’t want to buy the wrong thing only to regret it later, and if strange odors ruin the house for me, it will be skipped and instead operated with humidifiers as needed… Quite simple…
The only positive thing in your last post was about youth, which almost makes an old geezer happy who likes to indulge in luxury for his hard-earned money, of course always ;).
